Abstract: Disclosed is a system and method to both reduce a degree of explosive shock waves and to absorb a degree of explosive blast energy from the undercarriage of a vehicle which comprises the use of one or more layers of rigid closed-cell spray polyurethane foam, applied to the armored undercarriage of the vehicle. This invention combines two key aspects: 1) blast suppression or mitigation materials that absorb energy and 2) traditional military hardened armor solutions. The effectiveness of spray applied rigid foam has been proven to both dramatically reduce shock waves and absorb energy from explosive blasts (e.g., IEDs).

Abstract: The present invention relates to a method, processes and system that allows thermal insulating and waterproofing of temporary and/or portable structures in such a manner that the underlying structures are insulated and waterproofed. Moreover, this system provides a rigid outer structure which allows the underlying structure to be removed and reused after the insulation and waterproofing system has been installed, leaving behind a rigid, insulated and waterproof physical structure.
